I have a 7 month old Jackson Chameleon, and both joints on his right front limb are very swollen, as well as his knee joint on his back right limb. I feed him regurarly, and make sure i proportion all his calcium and vitamin treatments as recomended. I do not think it is MBD because he is able to move about and grip just fine. His color is still fine as well, and he still loves to get out of his cage and move around on the ficus plant i have sitting on my end table. Is there a posibility of a break or infection wit no behavior out of the ordinary?
